It's pointless to place bets without seeing the list of templates. If there are three XL templates (Heroes of Might and Magic VI, Legends of Might and Magic, Heroes of Might and Magic X), then that's one prediction, but if it's a mix of random maps like Panic, SMK, and Balance, then it's a completely different prediction, close to an equal chance.
2. Cobra.
Stinger has won Chaos League tournaments on XL maps; he has a lot of experience.
I don't know about Pete; I doubt he has that much experience.
They'll probably agree on what to play.
But it would be very interesting to watch. )
